BENCH-PLANE.

SPECIFICATION forming part Of Letters Patent No. 510,096, dated December 5, 1893.

Applicationfiled May 21,1892.

To all whom it may concern:

Be it known that I, J ACOB SIEGLEY, a citizen of the United States, and a resident of Wilkes- Barr, in the county of Luzerne and State of Pennsylvania, .have invented certain new. and useful Improvements in Bench-Planes, of which the following is a specification.

This invention relates to certain improvements in bench-planes, and the same consists of a cast-iron bottom and steel side-plates riveted to lugs of said bottom, and of a cap that is provided with a shoulder having setscrews, said shoulder resting on a transverse rod extending between the sides of the supporting frame and screws in said shoulder permitting the adjustment of the cap into higher or lower position, all of which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved bench-plane. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a detail vertical transverse section on' line 3 3, Fig. 2. Fig. 4 is a bottom view of the front part of my improved bench-plane, and Fig. 5 is a perspective view of the throat-piece as detached from the plane.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the frame of my improved bench-plane, which is composed of a cast-iron bottom plate a, provided with lugs a, that are castintegral there with, and of upright steel side plates a. which are attached by rivets that are inserted into I the lugs or bosses a, as shown clearly in Fig. 3. Bymakingthe sidesof steel platesamuch lighter and more durable frame forbench-planes is obtained. To the rear part of the bottom plate a is attached the main handle H, while the knob hat the front end of the plane is provided with a spindle h having a threaded lower end that takes into an interiorly-threaded boss B of a detachable throat-piece B which is supported against the under side by the front part a of the bottom of the frame A, said bottom being a short distance from the lower edge of the frame, so as to provide for the throat piece B and bring the under side of the same accurately at a level with ing through the throat of the plane.

the under side of the main part of the bottom plate a, as shown in Fig. 2. The throat piece can be adjusted toward the blade 0 and cap D of the latter, as the boss of the same permits the shifting action to a certain extent in the opening of the front'part a of the bottom plate, the knob h with its spindle h serving to tightly retain the throat piece on the front part a of the bottom plate. The rear end of the throat piece is provided with an upwardly inclined flange I), along which the shavings pass, as they are cut off by the edge of the blade, the said flange guiding the shavings and preventing them from curling in passing up through the throat of the plane. The cap D is made tapering at its lower end, so as to bear on the blade C, while the upper end is provided with a screw D by which the blade 0 is rigidly held in position in the stock of the plane. The under side of the blade is provided with transverse grooves m that are engaged by the tooth c of a fulcrumed arm E, the forked lower end E of which is engaged by a collared sleeve F that is adjustable on a fixed screw G'on the fixed block J of the frame A so as to adjust thereby the blade in the stock. The cap D is provided with shoulder at which rests against the transverse rod d that connects the upper part of the steel side plates a as shown in Fig. 2, said shoulder being provided with set-screws d the lower ends of which bear against the transverse rod 01' said set-screws serving for raising or lowering the cap, so as to adjust it 8 5 accurately in its relative position to the blade. The under side of the main part of the bottom plate, a and the under side of the throat piece B are provided with longitudinal corrugations fby which the friction of the bottom of the 9': plane with the surface to be planed is'considerably reduced and an easierworking than with the solid smooth bottom produced. I

The bench-plane described is light and durable and the shavings are not curled in pass- 5 tom corrugations facilitate the working of the plane, while the cap can be adjusted into higher or lower position, so that it is readily adjusted into its proper relative position to the plane, even as the cutting edge of the same is ground off by use.'

Having thus described my invention, what transverse rod and setserews passing through I claim as new, and desire to secure by Letters said shoulder so as to permit the adj nstment Patent, isof the cap relatively to the blade, snbstan- 15 1. A bench-plane, the frame or stock of tially as set forth.
